Specification of Letters Patent.

Application filed May 19, 1904. Serial No. 208.661.

T at whom it may concern.-

Be it known thatI, GEORGE A. HOLMES, of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Fasteners, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to that class of fasteners consisting of a stud or button member and a socket or buttonhole member; and it consists in a stud or button member embodying certain new features of construction hereinafter shown and described.

Referring to the accom Figure 1 shows in section t e two parts of my improved stud member as they are commercially sold. Fig. 2 shows in section the two parts of my improved stud member placed together with the material between them prior to being riveted together. Fig. 3

'- shows the Same after the operation of riveting has taken place. Fig. 4"showsa plan of the bird-cage or resilient stud, and Fig. 5 Shows a side elevation of same. Fig. 6 shows in section a modification of my improved stud member before assembling, and

. from the center or point Fig. 7 shows the same complete.

As shown in the drawings, my improved stud member consists of the stud A and the dome attaching-eyelet B. The stud A has the struck-up bird-cage X, Figs. 4 and 5,) the collet attaching bottom plate Z. The bird-cage X is preferably struck up, as usual, from a starshaped piece of metal, the radiating arms thereof being of substantially uniform width of juncture to their ends, as distinguished from having at their respectiveends enlargements contacting with each other to prevent collapse. The collet serves to connect, as shown, the ends a: of the arms of the bird-cage X and the periphery z of the convex' bottom plate Z. In Figs. 6 and 7 I Show a modificatlon in which I use an integral combined collet and convex bottom plate which may serve the purpose of the two corresponding pieces shown in Figs. 1, 2, and 3.

The dome attaching-eyelet B has the hollow dome b and the flange b, the dome b being of such diameter as to just pass easily through the opening 2 of the convex bottom plate, as shown in Fig. 2. When the two arts are placed together with the material Eetween them, as shown in Fig. 2, and pres- (shown by itself in Y, and the convex anying drawings,

' ri heral flanged ends, and

sure applied in any suitable manner, the convex bottom plate Z, which also serves as a biting part, is flattened, contracting the central opening 2 and biting into the dome b of the attaching-eyelet, as shown in Fig. 3, with the result that the dome or shank is indented and the two parts are firmly riveted together onto the material. At the same time the dome b fills the interior of the bird-cage sufliciently to prevent its collapse by the withdrawal of the endsof the bird-cage from the collet when the stud member is snapped into a suitable socket member. Heretofore in making bird-cage or resilient stud members of the form shown resort has been had to various devices in the manufacture to prevent this collapse, such as inserting a fixed dome or filler within the bird-cage and also by providing the ends of the sprin -arms with circumferential ends or feet which when ,inclosed in the collet meet and form a continuous flange at the base of the bird-cage. By the construction of my improved stud member I do away with the necessityof roviding the bird-cage as sold with any internal support or collapse-preventing device, for during the process of manufacture a suitable pin can be inserted within the bird-cage while it is being formed, and after the setting the dome of the attaching-eyelet performs this necessary function.

What I claim as my invention is In a stud member the combination of a eyelet portion, said eyelet having a flange adapted to clamp the material, on the lower side of the material, and a shank to be eX- tended through an aperture in the flap and far enough to enable its use upon varying thicknesses of material, the said eyelet being closed above; the other portion consisting of the bird-cage or analogous spring, having a hollow interior sufficiently large to receive the upper portion of the eyelet-shank, the spring fingers clamped around their eincapable of loose p ay, and a iting member which is formed rigid with the bird-cage spring, comprising an inverted crater-shaped apertured metallic biting part, adapted, by simple pressure between the parts, to be flattened and its a erture contracted to so bite into the shan of said eyelet at any portion of the latter; the shank of said eyelet, from flange to crown being of uniform diameter equal to the diameter of the aperture in the glove-flap and capable of being bitten into by said biting part a said material, whereby the material is tightly pinched or clamped, whatever be its thickness, simultaneously with the securing with each other, about the material, of the two portions of said stud.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 17th day of May, A. D. 1904.
